Sen. Al Franken has asked Google to explain what it does with the personal, private data of students who use its Google Apps for Education products and Chromebooks.

Franken wrote Wednesday to express concern that Google may be collecting students’ personal data for non-educational purposes without parents’ knowledge or consent.

“I believe Americans have a fundamental right to privacy, and that right includes a student or parent’s access to information about what data are being collected about them and how the data are being used,” Franken wrote.
